Disc stand

ABSTRACT

In a disc stand device, a pyramid-shaped or cone-shaped support column ( 2 ) is provided to be longitudinally placed in an appropriate position. A plurality of slits ( 4 ) are provided to align at regular intervals on an elevational side or a ridgeline of the support column ( 2 ) along a longitudinal direction of the support column ( 2 ). The slits ( 4 ) have a depth directed to tilt to form an acute angle against a generating line of the support column ( 2 ). Upon inserting the disc plates ( 5 ) into the slits ( 4 ), the plurality of disc plates ( 5 ) overlap partially when viewed from the user side. This enables the user to take out the desired one quickly by visually confirming the title through the gap between the disc plates ( 5 ) arranged adjacent vertically or laterally. When the disc plates ( 5 ) are applied to computer-related devices, it is possible to significantly improve an efficiency of the clerical work due to the disc plates ( 5 ) quickly taken out.

FIELD OF THE INVENTION

The invention relates to a disc stand device improved to convenientlyaccommodate and hold many types of disc plates which include a compactdisc, a mini disc, a flexible disc, a hard disc, an optical disc, or thelike.

BACKGROUND OF THE INVENTION

Among these types of disc plates, some have been called CD, MD and FDfor short, and often used to activate computer-related devices, registeror edite contents which the disc plates had once stored. After listeningto music, exchanging information or doing clerical work on thecomputer-related devices, it is common that the disc plates areaccommodated into an appropriate box-like drawer or a bookshelf so thatthe disc plates are taken out conveniently upon reusing the disc plates.Upon accommodating these disc plates, they are arranged to overlap sideby side in a latitudinal direction.

For the purpose of convenience, titles are generally labeled on each ofthe disc plates to easily identify the desired one. The overlapped discplates, however, obscures the title to make it difficult to find thetitles. This requires users to repeatedly take the disc plate out of thedrawer or the bookshelf and put it back until they confirm the desiredone. Thus, the repetitive taking-out procedures makes selectuion of thedisc plates troublesome and time-consuming so as to result in a goodefficiency of the clerical work being eroded.

Therefore, it is an object of the invention to overcome the abovedrawbacks, and provide a disc stand device which is capable of takingout the desired one quickly by visually confirming its title at the timeof reusing the disc plate, thus contributing to improving an efficiencyof the clerical work when the disc plates are applied tocomputer-related devices.

DISCLOSURE OF THE INVENTION

(1) According to the present invention, upon inserting the disc plateinto the slits, the plurality disc plates overlap partially when viewedfrom the user side. This enables the user to take out the desired onequickly by visually confirming the title through the gap between thedisc plates arranged adjacent vertically or laterally. When the discplates are applied to computer-related devices, it is possible tosignificantly improve an efficiency of the clerical work due to the discplates quickly taken out.

(2) Each of rectangular plates is slidably inserted into thecorresponding rectangular frames to render the rectangular platesdetachable against the corresponding rectangular frames. Depending onthe number of the rectangular plates inserted into the correspondingrectangular frames, it is possible to conveniently adjust the number ofthe slits, i.e., the mumber of the disc plates.

(3) Due to a geometrical structure that the support column is arrangedin parallel crosses with four rectangular plates, it is possible toattract the user's attention so as to advantageously make the user takeout the disc plate quickly.

(4) The support column forms a slope surface to be tapered off asapproaching upward, and a plurality of stepped portions are providedwith the slope surface to have the slits. This makes it possible toaccommodate the disc plates more due to an increased area of the slopesurface.

(5) The support column is shaped into a truncated-pyramid configurationwith the depth of the slits oriented in parallel with the generatingline of the support column. This mitigates a lateral interferancebetween the neighboring disc plates, and preventing the neighboring discplates from excessively extending vertically so as to insure aspace-saving advantage.

(6) Due to the support column arranged in free-wheeling relationshipwith a central shaft, it is possible to easily find the desired one byrotating the support column around the central shaft when taking out thedisc plate.

(7) Due to the support column, each elevational side of which forms aslope surface to be tapered off, it is possible to stabilize the supportcolumn, and accommodate the disc plates more due to an increased area ofthe slope surface.

(8) Due to the support column suspended in free-wheeling relationshipwith a central shaft provided on the support column, it is possible toeasily find the desired one by rotating the support column around thecentral shaft when taking out the disc plate.

(9) Due to rectangular plates, each one side of which is removablyinserted into the corresponding grooves of the support column, it ispossible to conveniently adjust the number of the slits, i.e., thenumber of the disc plates depending on the number of the rectangularplates secured to the support column. By leaving unnecessary rectangularplates removed from the support column, it is possible to render thesupport column into a space-saving structure.

(10) The longitudinal grooves are mortises, and each of the rectangularplates has a tenon slidably fit into the corresponding mortises. Thismakes the structure relatively simple and less costly when therectangular plates is removably attached to the support column.

(11) An opening side of the longitudinal grooves is predetermined to beslightly wider so that the rectangular plates move right and left in areciprocal direction with the tenons as central axis. This makes itpossible to easily find the desired one by moving the rectangular platesaround the tenon when selecting the disc plate.

(12) The support column is provided to have a plurality of lateral armsin a longitudinal direction. Lateral lengths of the arms areprogressively longer as approaching downward. A triangular sack issecured to each distal end of the lateral arms. A depth of the sack isdirected in parallel with the support colum or slantwisely directed toform an acute angle against a generating line of the support column. Thedisc plate is removably inserted at one portion into any of the sacks.

This reminds the user of a sail-ship structure to attract the user sothat the user can get accustomed to the disc stand device very soon.

(13) Trapezoidal plates are provided at ridgelines of the supportcolumn, each slope side of the trapezoidal plates has a plurality ofslits laterally extended and aligned in the longitudinal direction atthe neighboring trapezoidal plates positioned in parallel each other.The slits have a depth directed to tilt to form an acute angle against agenerating line of the support column. The disc plate is removablyinserted at one portion into any of the slits.

The trapezoidal plates have a structural novelty to attract the userwhile accommodating the disc plates more due to an increased area of theslope surface.

(14) The support column is formed into a helically shaped configurationand diametrically smaller as approaching upward. The support column hasa plurality of slits laterally extended and aligned at predeterminedintervals along a helix line of the support column. The disc plate isremovably inserted at one portion into any of the slits.

This enables the user to easily take out the disc plate from and insertit into the slit, while at the same time, giving a good appearance andan ornamental effect due to a structural combination of the helicalcolumn and the disc plates.

(15) A lip plate is provided at an opening periphery of the slits sothat the lip plate elastically bends backward to slidably admit the discplate when the disc plate is inserted into the slit.

Due to the friction when the disc plate is slidably admitted on the lipplate, it is possible to prevent the lip plate from slippinginadvertently so as to stabilize the disc plate admitted into the slit.
